4 0

Answer: 4.2%

Step-by-step explanation:

  • The probability the first response is correct is 1/6.
  • The probability the second response is correct is 1/4.

Multiplying these, we get (1/6)(1/4), which is about 4.2%

f(x)= -2x+1 {-2,0,2,4,6}

If x=-2, then -2(-2)+1 = 5

If x=0, then -2(0)+1 = 1

If x=2, then -2(2)+1 = -3

If x=4, then -2(4)+1 = -7

If x=6, then -2(6)+1 = -11

Answer:

B {5,1,-3,-7,-11}

Given right triangle MNL, what is the value of cos(M)? Three-fifths Three-fourths Four-fifths Five-thirds
lidiya [134]

By applying the Pythagorean Theorem and the Trigonometry ratio, CAH, the value of cos(M) = 4/5

<em><u>Recall:</u></em>

Trigonometry ratios, <em>SOH CAH TOA</em> can be applied to solve a right triangle.

  • Pythagorean Theorem can also be applied which is: c² = b² + a², where c is the longest side (hypotenuse length).

<em><u>Given:</u></em>

ΔMNL is a right triangle

ML = 25

NL = 15

Find MN using the Pythagorean Theorem:

MN = √(ML² - NL²)

MN = √(25² - 15²)

MN = 20

To find the value of cos(M), apply the trigonometry ratio, CAH, which is:

cos ∅ = Adj/Hyp

  • Where,

∅ = M (reference angle)

Hypotenuse = ML = 25

Adjacent = MN = 20

  • Plug in the values:

cos(M) = 20/25

cos(M) = 4/5

Solvex - 8x= 3 by completing the square. Which is the solution set of the equation?
erastova [34]

Answer:

x = 4±sqrt(19)

Step-by-step explanation:

Assuming you meant x^2 -8x = 3

Take the coefficient of x

-8

Divide by 2

-8/2 =-4

Square it

(-4)^2 = 16

Add this to each side

x^2 -8x +16= 3+16

The number inside the square term is the coefficient divided by 2

(x-4)^2=19

Take the square root of each side

sqrt((x-4)^2=±sqrt(19)

x-4 = ±sqrt(19)

Add 4 to each side

x-4+4 = 4±sqrt(19)

x = 4±sqrt(19)
